Sheet-Piling, of which the following is a specification. v

The invention relates to improvements in metahsheet-piling; and itconsists in the novel features hereinafter described and claimed. I

The object of the invention is to produce a metal sheetiling of superiorcharacter and comprised o sections of novel form and construction, adating them for all theuses to which metal s eet iling may be put.

Among the speci 0 objects attained by my invention in its preferredembodiment it may be mentioned generally that the units or sections ofmy piling are strong, durable, and easily formed, that the sections areformed integrally with means whereby they may be locked together, thusdispensing with separate locking-flanges and the like riveted to thesections, that the sections are all alike in form and constructionexcept where corners are to be formed, and that a wall of piling formedof the interlocked sections presents, in the preferred construction, onone side a substantially uniform surface.

The invention will be fully understood from the detailed descri tionhereinafter presented, reference being fiad to the accompanfyingdrawings, in which Figure '1 is a top edge view of a metal sheet-pilingcomprising sections embodying my invention. Fig. 2is a face view, partlybroken away, of same. Fig. 3 is a detached top edge view of one of thesections of the piling. Fig. 4 is a top edge view of several sections ofthe piling and is presented to illustrate the formation of thecorner-sections which may be required when the piling is-required todefine angular outlines, and Fig. 5 is a top edge View of one of thecorner-sections.

in the drawings, referring to Figs. 1, 2, and 3, the.individual'sections of'the piling are designated by the numeral 10, andthese sections all correspond with one another and each is made from anintegral plate of metal fashioned to form the web 11 and edgelocking-loops 12 13 ,respectively, which referably both project from thesame side of t e web, so that the piling when the sections are assembledmay present at one side a substantially flat wall. The loops 12 13 aresubstantially cylindrical in cross-section, and both are formed bycoiling the edges of the metal plate into the outlines shown, theright-hand edge of the plate being turned outwardly,-forming a shortflan e14, and then coiled to form the loop 12, w 'ch projects beyond therighthand edge of the plate and is left partly open to form a mouth 15,adjacentto said flange 14. The 100 13 is formed by turning the left-hande ge of the plate outwardly, forming a flange 16, and then coiling themetal in a direction toward the right to form said loop, which ispreferably closed, or substantially so, as shown, and is of smallerdiameter than the loop 12, but of greater diameter than the mouth 15thereof.

The manner of assembling thesections 10 is illustrated in Fig. 1, inwhich it may be seen that the sections are driven one after another andthat the loop 13 of one section is driven within the loop 12 of the nextadj acent section, the flan e 16 passing through the mouth 15 of saidoop 12. I preferably allow considerable freedom between the outer wallof the loop 13 and inner wall of the loop 12. When the sections areassembled, the adjacent loops 12 13 enter'into locking engagement witheach other and resist any strains tending to separate the sections.

Figs. 4 and 5 are presented to illustrate the employment of the sections10 in the formation of piling requiring an angular course, in which useof the sections I employ cornersections 17, havingthe webs 11 and loops12 of the sections 10, andprovide on one edge thereof loops 18,differing slightly from the loops 13 of said sections '10 in that saidloops 18 are formed directly on the edge of the web and that the flanges16 are omitted, the Web itself passing through the mouth'of the loops12, as shown at the upper and lower righthand corners of Fig. 4.

The sections 10 are all alike in every particular, and the loops 12 13not only form integral locking members, .but by reason of their outlineconstitute means for stiffening the sections and enabling them to bereadily driven. The form of the sections 10 also enables theirproductionfrom plate with convenience and Without undue weight or wasteof metal.

If the loops 13 projected from the opposite side of the webs or in adirection oppositely .to the loops 12, they would cooperate with saidloops 12'just as shown in Fig. 1; but in that event neither wall of thepiling would be substantially flat or uniform, and therefore, Without inevery instance limiting myself to the same, I prefer to have the loops12 13 both projected from the same side of the web, as shown.

What I claim as my invention, and desire to secure by Letters Patent, is

1. A metal sheet-piling composed of interlocked plate-sections eachcomprising interally a web, a loop on one edge thereof ormed byflangingthe metal outwardly and coiling the same into loop form and leaving anarrow mouth of the-loop open, and a smaller loop on the opposite edgethereof formed by flanging the metal outwardly and coiling the same intoloop form, thesmaller loops of the.

respective sections being adapted to be loosely inclosed in the largerloops of the respective adjacent sections and enter into lockinengagement therewith; substantially as set orth.

2. A metal sheet-piling composed of interlocked plate-sections eachcomprising inte-v grally a web, a loop on one edge thereof formed byflanging the metal outwardly and coiling the same into loop form andleaving a narrow mouth of the loop open, and a smaller loop on theopposite edge thereof formed by flanging the metal outwardly and ceilingthe same into loop form, the smaller loops of the respective sectionsbeing adapted to be loosely inclosed in the larger loops of therespective adjacent sections and enter into locking engagementtherewith, and said loops of each section being extended outwardly fromthe same side of the section; substantially as set forth.

8. A metal sheet-piling composed of interlocked plate-sections eachcomprising inte- 'rally a web, a loop on one edge thereof formed bycoilin the metal into substantially cylindrical form and leaving anarrow mouth of the cylinder open, and a smaller 100 on the oppositeedge thereof formed by coi in the metal into substantially the form of aclosed cylinder, the smaller loops of the respective sections beingadapted to be loosely inclosed in the larger loops of the respectiveadjacent sections and enter into lockin engagement therewith;substantially as set forth;

4. A metal sheet-piling composed of interlocked sections each comprisingintegrally a web, on-one edge of which is formed a flange 14: andpartly-open loop 12 formed by coiling the metal plate in a directionfrom and beyond said web, and on the other edge of which web is a flange16 and loop 13 formed by coiling the plate in a direction toward saidweb, the smaller loops of the respective sections being adapted to beinclosed within the larger-loo s of the respective adjacent sections anenter into locking engagement therewith; substantially as set forth.
